Here is what I found for IHD. I am not a doctor so cannot comment but if it fits in here then you may have something to claim.
"According to Harrison's Principles of InternalMedicine (Harrison's
Online, Chapter 237, Ischemic Heart Disease, 2008), IHD is acondition
in which there is an inadequate supply of blood and oxygento a portion
of the myocardium; it typically occurs when there is animbalance
between myocardial oxygen supply and demand. Therefore, forpurposes of
this regulation, the term ``IHD'' includes, but is notlimited to,
acute, subacute, and old myocardial infarction;atherosclerotic
cardiovascular disease including coronary artery disease(including
coronary spasm) and coronary bypass surgery; and stable,unstable and
Prinzmetal's angina. Since the term refers only to heartdisease, it
does not include hypertension or peripheral manifestationsof
arteriosclerosis such as peripheral vascular disease orstroke.
